Cool correction...How to you correct for the purple fringing? I have some pics I would like to remove it from.
(don't tell me to search for it!)
This is the quick and dirty method, as you can see there's still some purple fringing and I didn't really take care of the red chromatic aberration since I liked the effect it had.
Anyhow, use a masked hue/saturation adjustment layer. Select magenta and use the eye dropper to center the right hue and desaturate as much as you feel necessary; in this case, I also reduced the lightness a bit.
Now use the mask to select only the areas that you want desaturated, so that you don't lose the legitimate purple hues in the image. I usually use a fairly small brush with ~50% opacity and ~75% flow, but this is highly variable to the image. Experiment with brushes to see what works best.
As for the rest, if you're interested, I adjusted the curves a bit so that that image would be slightly more punchy (especially given that all the extreme highlights were blown anyway.
I also fixed the weird reflection near the moon.
Finally, a quick USM makes the image look just a touch sharper.
